Hydroprocessing
Hydroprocessing uses hydrogen and catalysts to remove impurities and break down molecules to improve the quality and value of fuels. We have achieved significant advances in hydroprocessing, including the development of high-conversion technologies for upgrading heavy residues (like LC-Finning) and innovating technologies for bottom-of-the-barrel upgrading that minimize capital and operating costs. Our technologies have been successfully implemented in more than 100 hydroprocessing plants, including the world’s largest all-hydroprocessing white oil unit.
ISOCRACKING
The most flexible upgrade path to lighter products
Our ISOCRACKING technology converts heavy hydrocarbon feedstocks into high-yield kerosene and diesel. The technology is paired with ISOCRACKING catalysts to offer refining companies the most flexibility in buying decisions and allow for a wide range of product production. ISOCRACKING catalysts provide high temperature stability and proven performance with high endpoint and high nitrogen feeds. Our designs are suitable for multiple plant configurations, making ISOCRACKING a cost-effective way to achieve higher yields at existing facilities and build state-of-the-art new units.
What sets our tech apart:
- Highest feedstock flexibility with highest yields
- Proven reliability
- Operations-oriented designs
- Amorphous, amorphous/zeolite and zeolite catalyst technology
- Optimized reactor systems
- Advanced internals technology
- Low fuel consumption
ISODEWAXING
More yields, more products
Our revolutionary ISODEWAXING process helps refining companies upgrade paraffinic streams into high-viscosity index base oils for lubricants. It enables refiners to capture more value from hydrocracker bottoms by producing premium-grade engine oil feedstocks. The ISODEWAXING Catalyst lowers processing severity in the hydrocracker and further increases yields. This process significantly improves catalytic dewaxing and easily outperforms solvent dewaxing because it preserves the feedstock’s paraffinicity. ISODEWAXING allows refiners to process feedstock with slack wax and hard wax into a broad range of products.
What sets our tech apart:
- Isomerizes the molecular structure of wax rather than removing it
ISOTREATING
Removing impurities for cleaner fuels
Our ISOTREATING technology helps refining companies remove sulfur, nitrogen and other impurities from hydrocarbon feedstocks such as naphtha, diesel, kerosene and vacuum gas oil. ISOTREATING uses lower temperatures and pressures than ISOCRACKING to separate products without altering their molecular size. Supported by advanced catalyst systems, ISOTREATING helps refiners produce cleaner fuels, improve downstream performance and meet environmental standards at lower cost.
What sets our tech apart:
- Minimal emissions and waste effluent
- Minimal by-product formation
- Catalyst use results in small reactors with high-quality product
Residue Desulfurization
Reducing sulfur for environmental and economic benefits
Our residue desulfurization (RDS) process is a high-pressure catalytic hydrotreating process that helps refiners lower sulfur levels in crude oil (vacuum) residues to produce cleaner fuels and feedstocks. This hydrogen-efficient process sufficiently saturates products so that further processing in conversion units is greatly enhanced, ultimately producing more and higher-value light products. Adding an Onstream Catalyst Replacement (OCR®) unit enables refiners to significantly increase capacity or improve product quality from the RDS unit. As a globally dominant technology, it helps refiners meet strict environmental regulations while improving economics.
LC-FINING
Making difficult feedstocks profitable
Our LC-FINING ebullated-bed process converts extra heavy crude oil (vacuum) residue into low-sulfur, low-metals hydrocracker feedstock. Our process reduces capital investment by using a proprietary, low-pressure hydrogen recovery system as opposed to high-pressure equipment. A built-in onstream catalyst addition and withdrawal system reduces operating expenses by eliminating shutdowns for catalyst replacements. With high yields and long run lengths, LC-FINING allows refiners to turn the most difficult feedstocks with the heaviest fractions into light, clean products and high-value transportation fuels.
What sets our tech apart:
- Low investment
- More light-ends recovery
- Lower operating costs
- More efficient heat recovery
- Lower hydrogen losses
- Lower maintenance
- Maximum conversion to light clean products
- Integrated fuels hydroprocessing
Conversion
Our conversion processes change low-value, contaminated waste feedstocks into high-value renewable fuel products. We focus on transforming unusable heavy residues into useful light gas oil products and coke. The benefits of this approach are both economical and environmental.
Delayed Coking
Transforming unusable residues into useful, light, gas oil products and coke
Our delayed coking process is a thermal cracking process that converts heavy crude residues into lighter gas oils and solid petroleum coke. The delayed coking unit design features online computer control, fully enclosed automatic unheading, single- or double-fired heaters, state-of-the-art coke drum mechanical design, vertical plate coke drum technology, helical baffle exchanger in fouling services, and an innovative water management/coke recovery system. The process can handle a variety of feedstocks, such as petroleum derived residues, cracked materials, and liquid feedstocks derived from coal. Our design maximizes distillate yield while meeting downstream hydroprocessing unit requirements. Delayed coking provides refiners with a proven, flexible way to maximize fuel production from bottom-of-the-barrel streams.
Solvent Deasphalting
A cost-effective upgrade for fuel products and base oils
Our solvent deasphalting process allows refining companies to maximize high value fuel production by removing heavy asphaltenes from petroleum liquids to produce deasphalted oil (DAO). We use a specialized solvent extraction process that separates DAO from contaminants in the residue by molecular type instead of by boiling point. The DAO can be used in fuel or upgraded into base oils, offering refiners a flexible tool to convert bottom-of-the-barrel residues and extract more value from heavy feedstocks.
What sets our tech apart:
- Unique renewable application
FCC
The flexible conversion workhorse of refining
Recognized as one of the most efficient and reliable processes in the refining industry, our Fluid Catalytic Cracking (FCC) technology allows refiners to convert heavy vacuum gas oils into high-value motor fuels. The process is flexible, allowing refiners to shift yields between maximum gasoline and maximum diesel. Proprietary, commercially proven features like Micro-Jet Plus™ feed injectors, the patented Reaction Termination Device, and MSO™ combustion air distributors work together to enhance cracking, improve reliability, and ensure superior performance.
